The Hubble Space Telescope has peered deeper than ever before into the heart of the supermassive black hole-powered quasar 3C ...

Not long ago, the James Webb Space Telescope (JWST) peered into Cosmic Dawn, the cosmological period when the first galaxies ...

Some different correlations between optical-UV variability and other quasar properties, such as luminosity ... We suggest that the accretion disk model can explain these correlations, provided the ...

Quasar jets that can be detected using very ... The direction of the jet near its source tells us about the orientation of the accretion disk, and so potentially the properties of the black ...

The light from this quasar has travelled over 12 billion years to reach Earth, offering astronomers a glimpse into the early universe. Its incredible brightness comes from a hot accretion disc ...

This “accretion disk” in turn generates a super-heated ... When a supermassive black hole lights up like this, we call it a quasar. To get a good look at quasar jets, astronomers often use ...

The Hubble Space Telescope has delivered a stunning new perspective on one of the most famous quasars in the cosmos, 3C 273, ...

This still from the simulation shows a supermassive black hole, or quasar, surrounded by a swirling disk of material called an accretion disk. Credit: Caltech/Phil Hopkins group Astounding simulation ...

NASA's discovery of massive black holes like the one in quasar 3C 273 offers new insights into galactic interactions and how ...

(4) The wavelength dependence of the IRAC flux ratios is consistent with the standard quasar model in which an accretion disk and a dusty torus both contribute near 1 micron in the rest frame. This is ...

We present a new technique for probing the kinematic properties of the BELR and accretion disc of high-z quasars using differential microlensing, and show how substantial information can be gained ...

Quasar jets that can be detected using very ... The direction of the jet near its source tells us about the orientation of the accretion disk, and so potentially the properties of the black ...
